Preparation

Preheat oven to 350 degrees. Spray a 9 X 13 inch baking dish with cooking spray. Place eggs (5 whole eggs and 5 egg whites, discard unused yolks), milk, salt, pepper and garlic powder in a large mixing bowl and whisk together. Place a large skillet over medium heat. Add oil, onion and peppers and stir. Cook for 1 minute, then add mushrooms and stir. Cook for another minute, then add zucchini. Stir and cook for 1 minute, then add asparagus. Stir together and cook for 1 to 2 minutes until asparagus are crisp tender. Arrange vegetables in the baking dish. Pour egg mixture over vegetables. Top with Parmesan cheese and bake for 35 minutes until a toothpick in the center comes out clean. Remove from oven and top with grated cheddar. Let rest for 10 minutes before cutting.
